IMPORTANT:Use caution when working with Li-ion cells, they are very sensitive to charging characteristics and may explode or burn if mishandled. Make sure the user has enough knowledge of Li-Ion rechargeable batteries in charging, discharging and assembly before use. Always charge in or on a fire-proof surface. Never leave charging batteries unattended. We will not be held responsible for damage if there is any modification of the batteries/chargers in any form. We are not responsible for any damage caused by misuse- or mishandling of Li-Ion batteries and chargers.
Never completely discharge battery (below 2.5V under load or 3.0V unloaded)
Charge Fully (to 4.2V) before first use
Never use a lot of strength on battery installation
Use only proper battery chargers that’s designed for 18650 type of battery
Do not expose to heat / sunlight
Do not connect the positive contact to the negative contact without an appropriate load
Be aware of the current limits in the specification and never exceed the number
Never keep a spare battery loose in a pocket, purse, backpack, or etc… Always use proper case for loose batteries. If it shorts against a piece of metallic material, it can be dangerous
Never charge the battery up to 4.3V or above
